WHIFFLETREE-HOOK.

SPECIFICATION forming part of Letters Patent No. 501,002, dated July 4, 1893.

Application filed October 19, 1892. Serial No. 449,351 (N0 mOdBl-l To all whom it may concern:

Be it known that I, GEORGE C.EDMUNDs, of Rochester, in the connty of Monroe and State of New York, have invented a certain new and useful Improvement in Tug-Holders for I-Iarness; and I dohereby declare that the following isafull, clear, and exact description of the same, reference being had to the drawings accompanying this specification.

ro My improvement relates to that class ot' tug holders in which a lever is used on the end of the whiftletree to prevent the tug from sli p- My invention consists of a lever made in a single'length with open reverse hooks at the opposite ends in which the tug can be inserted sidewise by twisting the same, and provided with a central loop which embraces the whif- 3c iietree, forming the pivoted bearing to the same, also a gage which limits the movements in opening and closing.

In the drawings Figure 1 is a perspective view ot one end ot' a whiflietree showing my improvement attached. Fig. 2 is a plan View exhibiting in full and dotted lines the position of the lever when fully opened and closed. Fig. 3 is a side View of the lever.

A indicates the whiiiietree and B the tug. 4o The tug is slipped over the end of the whit'- letree in the usual manner.

C is the lever for holding the tug in place. It consists of two single arms a, a with open reverse hooks b b at the ends, and a central v open loop c which embraces the whiiiietree,

and is pivoted thereto by screws d d, so that the lever can turn. The two arms d a, are in planes at such distance from each other that one rides below and the other above the whifiietree, and the hooks also point in opposite 5o directions, that at the outer end extending upward and that at the inner end extending downward as shown.

To attach the tug in place it is twisted a halt' turn to be entered bodily in the outer 55 hook, is then inserted over the end of the whifetree, and the projecting bight or end is then half twistedin a similar way to insertit in the inner hook. The strain on the tug causes the lever to turn and bind the trace in 6o place at both points of attachment.

Theloop c not only serves as a bearing by which the lever is pivoted to the whiletree, but also asa gage to limit the swing of the lever. It stands in an inclined position, approximately in line with the lever itself. In the closing movement to fasten the tug in place the loop strikesthe face of the whiflietree and prevents the hook from closing clear up, while in the opening movement the loop 7o strikes in the opposite position and holds the lever half way open. These two positions are indicated by the full and dotted lines in Fig. 2.

Having described my invention I do not claim broadly a clamp for holding the trace and its loose end or bight; nor do I claim in this application a lever provided with an angular gage for limiting its movement, such as shown in my pending application tiled February l2, 1892, Serial No. 421,266. 8o

What I claim as new, and desire to secure by Letters Patent, is-

The trace holder comprising the lever C consisting of the arms da standing in diierent planes, the open reverse hooks b b at the 8p ends ot' said arms, and the central V4oblique loop c forming thepivot bearing and a gage to limit the swingvof the leverin opposite directions, as herein shown and described.

In witness whereofI have hereunto signed 9o my name in the presence of two subscribing witnesses.
